“…LTE-advanced or LTE-A arrived with 3GPP Release 10, which focused on enhancing the network capacity using carrier aggregation techniques [20]. It enhanced the overall bandwidth of existing cellular networks by combining two or more component carriers for higher data rates [58]. Coordinated multipoint transmission and reception (CoMP), and heterogeneous deployments (HetNet) are supported since 3GPP Release 11.…”

Device-to-device (D2D) communication is rapidly evolving into a viable method of information exchange in a cellular network. It has a very low end-to-end latency and can increase spectral efficiency of a cellular network. The latest releases of 3GPP specification have given considerable attention to standardize this mode of communication and integrate it in the ecosystem of LTE advanced. This will give more impetus to the development of D2D technologies and their adoption by mobile operators. This paper presents a discussion and critical analysis of the main features of D2D communication as defined in Release 12 and subsequent releases of 3GPP specifications.

“…To achieve higher resource utilization, a CS scheme, termed as separated random user scheduling and separated burst level scheduling, is proposed with acceptable complexity [9]. In [10], a DAC scheme is proposed to provide better resource balance in wireless networks for elastic traffic using IBS; however, this method is impractical due to the change of primary CCs to idle CCs. Moreover, in this method, the packets are served by primary CCs as long as the queue of any secondary CC becomes empty, which increases the average sojourn time.…”

“…Hence, a well-designed CS scheme is essential to meet the reliable transmission and low cost of deployment in LTE-A systems. Different carrier scheduling algorithms [5][6][7][8][9][10][11] have been proposed, which schedule users depending on the available bandwidth to enhance the throughput of the system. Unfortunately, all the existing CA-based CS schemes barely take the delay requirements of real-time mobile multimedia applications into consideration.…”

Abstract:Carrier aggregation (CA) in long-term evolution advanced (LTE-A) networks is a promising tool for providing bandwidth extension for high data rate communication. In CA, the efficient scheduling of carriers has imposed a new challenge in the design of delay-sensitive carrier scheduling for mobile multimedia applications. In this paper, a new dynamic slot-based carrier scheduling scheme has been proposed for efficient resource allocation to support the quality of service (QoS) of mobile traffic over CA transmission. The key idea of this scheduling is the allocation of slots for each component carrier based on the queue state information, taking into consideration the priority based on the delay requirements of individual mobile multimedia traffic. Two different cases of the scheduler with and without priority are implemented to facilitate the performance comparison. The simulation results show that the proposed scheme provides better spectrum utilization, throughput, and delay performance than the existing scheduling scheme and improves delaysensitive mobile traffic QoS.

“…That is to say, interference has multidimensional characteristics. Although some references [6], [7] consider multidimensional interference management, they lack accurate mathematical representation of interference. In addition, when analyzing and optimizing the performance of wireless networks, it is often necessary to model interference through abstraction [8].…”

With the diversification of the kinds of wireless transmission service, the transmission rate and reliability of wireless communication have been demanded sharply. The shortage of resources of spectrum has become continuously prominent. These are bottlenecks to restrict the development of wireless communication. The current multi-antenna cooperative relay communication system can't sense complex communication scenes agilely, and adjust the strategy of interference suppression according to the signal characteristics adaptively, and optimize the resource of the system dynamically. Moreover, the degree of freedom and transmission system reliability should have been further improved. Aiming at the above problems, this paper extracts the features of the combined signal from different degrees of freedom, considering the influence and effect of the distribution characteristics of the signal on its separability, and signal spatial structure to enhance the ability to adapt to complex environmental interference. It explores multiple interactive cooperative transmission scheduling to optimize the wireless resource dispatching and new network coding jointly, and get a unified multi antenna relay transmission processing standards and to improve the efficiency of information transmission. It carries out theoretical studies of interference coordination algorithms which can acquire higher forwarding efficiency at relay in the view of energy efficiency and spectral efficiency.
